Nice review of The Technician here. Interesting in that it is from someone who is fairly new to my books:

As a relative newcomer to the Polity universe, with this only being my second Asher book, I wasn’t sure how well I’d be able to follow the story. I was in for a pleasant surprise. Although the story does take a while to get started and I struggled a little with the technology of it, I thoroughly enjoyed the read.
